Worms don’t grow according to a business calendar—and that’s an important gardening lesson, too. The new wormery follows a simple rhythm: pre-compost, breed, hatch, grow, hold, sell. During the first year, we’ll measure how much material the worms eat, how quickly cocoons hatch, how long growth takes, and how much space the system really needs. Temperature, moisture, food, bedding, and population density all shape the timeline.

Read our practical guide to help keep your composting worms comfortable, active, and productive all season long:

At our Oakley property, we’re using a light compost top-dressing on sandy lawn soil and layering worm castings, compost, and mulch in a new herb garden. See how these materials support soil biology, moisture, and heat resilience over time. Read the full post: https://deltaworms.com/2026/08/compost-and-worm-castings-healthy-soil/
